Here is a reduced test case for the duplicate SAVE attribute:


module datetime_mod

    implicit none
    save

    type :: DateTime
    end type

contains

    character function getString (dt)
        class(DateTime) :: dt
    end function 

end module


At first glance I would save this is invalid, and should be rejected with an
error. In particular, is it allowed to give a lonely SAVE statement? If yes,
what effect should this have? Usually SAVE is specified as an attribute for a
specific variable, right?
